Just H4350 and RL22 right now. I wasn't impressed with H4831sc in my Model Seven 260 for accuracy or velocity. The RL22 pushed a 129 gr SST to just shy of 2900 out of a 20" tube.

I was going to run a ladder with the H4350 and the RL22, just didn't have a start or max point for either. I have data for H4350 for 140 gr bullets, but nothing similar in design to either the Accubond or VLDs. What I have is for the flat base lead spitzer. I suppose I could work with the 140 or 142 SMKs' data, but I don't think RL22 is listed in any manual I have for 140 grain bullets.

EDIT: I have the Speer manual that came with my press kit, not Sierra.

RL-22 43-46.5gr
My 260 doesn't seem to be capable of high speed loads, with the 22" barrel a fast load for me in 130-140 gr bullets is 2850 fps. The 140 grain stuff shoots incredibly accurate down around 2600 fps

I'm hoping to have time to run a test with H4350 and RL22 for the Bergers and the Accubonds tomorrow, but I don't know if I'll have time to get it all in. I just want to find the "accuracy window" for each bullet/powder combo and then I can head back to the range another time to break that down further.

I got a snapshot from a Hornady manual and it has RL22 for the 140s - 38.6 - 46.6. I'll try the range listed above to save me a few rounds and time. I'm hoping for tight groups around 2900 fps with the 140s. That keeps KE above 1000 and velocity above 1800 fps with the Bergers out to 700 yards. That should be plenty of range to kill deer where I'm at in PA.

On the H4350...I see the data suggested here, but on Hodgdon's data on their website, the 140 gr Nosler Partition is listed at 39.0 - 42.0 grains and the 142 Sierra HPBT is listed at 41.5 - 44.5 grains. I'm guessing I could start with 42.0 as the Accubond and Berger are closer in design to the Sierra than the Nosler Partition and check every piece of brass for pressure signs.
